Yoshiko Hara, EE Times, reports:
TOKYO Nippon Telegraph and Telephone Corp. (NTT) has developed a diamond semiconductor device that operates at 81 GHz frequency, more than twice the speed of earlier devices. The advance promises to make amplification in the millimeter-wave band from 30 to 300 GHz possible for the first time, NTT claimed.
Diamond is expected to be the next generation semiconductor material because of its high thermal conductivity, high breakdown voltage and high carrier mobility. Together, these characteristics makes diamond semiconductors most suitable for high frequency, high power devices.

In the midst of the fighting, he noticed that the Americans had called up an oddly configured tank. Then to his amazement the tank suddenly let loose a blinding stream of what seemed like fire and lightning, engulfing a large passenger bus and three automobiles. Within seconds the bus had become semi-molten, sagging “like a wet rag” as he put it. He said the bus rapidly melted under this withering blast, shrinking until it was a twisted blob about the dimensions of a VW bug. As if that were not bizarre enough, al-Ghazali explicitly describes seeing numerous human bodies shriveled to the size of newborn babies. By the time local street fighting ended that day, he estimates between 500 and 600 soldiers and civilians had been cooked alive as a result of the mysterious tank-mounted device.
